GRAIN-BINDING MACHINE.

SPECIFICATION forming part of Letters Patent- No. 258,114, dated May 16, 1882.

Application med January 17, lesa. (Model.)

To all whom. it may concern Beit known that I, JOSEPH R. PRESCOTT, ot" Beaver Dam, in the county of Dodge and State of Wisconsin, have'invented certain Improvements in Grain -Binding Machines, of

which the following is a specication.

This invention relates-to a binding attachment for reaping-machines; and the improvements consist in guards or fenders applied to 1o the ordinary reaper-plattorm to direct the grain and insure its delivery into the compressor; in a (,:ylindricall compressor one section ot` which is sustained by a yielding or elastic support to permit it to accommodate different-sized gavels t5 and properlycompress them while being bound, and which is permitted to fall and discharge the bound bundle; in a novel method ot' and mechanismfor securing or fastening the ends of the applied bands, and in various other de- 2o tails hereinafter fully set forth.

In the accompanying drawings, Figurelrepresents a perspective `view of my improved attachment, showing also a portion of the-reaperplatform; Fig. 2, a plan view of the reaper e5 platform or table; Fig. 3,a top plan view of the machine or attachment; Fig. 4, an end view looking into the compressor; Figs. 5 and G, views illustrating the operationfof forming the knot; Fig. 7, a view of the completed knot, 3o and Fig. 8 an enlarged view of a feedingdevice hereinafter referred toand explained.

"In this machine the ends of the applied band are tied into a knot ot' peculiar from, and in order to prevent the knot from drawing or slipping out the strands of thc band are passed through and tied about an independent strip ot' material. The grain to be bo'und is swept by the ordinary sweep-rake directlyinto the compressor through its end and caused to pro- 4o ject therefrom into an open-ended cylinder provided with a cord-carrier, which passes the band about the bundle. lhe cord or twine passes from the reel to the cord-carrier, which `swings around the bundle, carrying the cord with it and laying the two strands in position to be seized and manipulated by the tying devices. The various lnotions are imparted to the machine from a main driving-shaft, which in turn is driven from the main drive-wheel of 5o the reaper. Referring now to the drawings, A represents the framing ofthe binding attachment, which maybe applied and secured tothe reaper in any convenient manner, and B the grain table or platform ofthe reaper. As shown in Figs. 1 and 55 2, the table or platform is furnished with uprightguards or guides a a', which start respectively at opposite ends ot' the sickle-bar and gradually approach each other until they terminate at the delivery side of the table at 6o such distance apart as to cause the grain to be delivered between them en dwise into the compressorO. Theseguardsorguidesaredesigned to be applied to the ordinary reaper-platform without any modification or alteration of the same or ofthe rake which sweeps over it; and inorder to permit the teeth or lingers ot' the rake to pass the guardsor guides, they (the guards) are provided with openings Z at such points as would otherwise be struck by the 7o teeth or ngers. The compressor O, into which the grain is delivered end first, is composed of two semicylindrical sections, thelower one of which, C, is hinged to the upper section, and is held normally in the position shown in Fig. 1 by a cam, D, on the main drive-shaft E, bearing upon a lever,F, connected with an arm, c, projecting` from the hinged section C in rear of its pivot or hinge. The connection between 8o the lever F and thejarm c consists ofan elastic or spring arm, F', and a chain or equivalent Hexible band or connection, which will permit ot' lengthening or shortening, to diminish or increase the force of the spring-arm and con-'85 sequent pressure upon the bundle in the compresser. The cam D serves to draw the hinged lower ,section of the compressor up to the position shown in Fig. 1 during the formation and binding of the bundle, thereby compress' 9o ing the same, butns the tying operation is completed and the applied band 'is severed from the band-stock the cam rides odil lever F and permits the section Oot` thc compressor to fall and dischargev the bundle. The mouth or receiving end ot' the compressor is preferably made flaring, as shown in Fig. 3,'tolinsure the proper entrance of grain into it, the grain being pushed through the same and caused to project therefrom into an open-ended cylinder, roo Gr, which serves to support theheads" duringthe binding operation, and which isfalso furnished with a cord holding and carrying device, H, by which the cord or band is passed around the grain and presented to the tying or fastening mechanism. The cylinder G is carried by a rock-shaft, I, to which an alternating rotary motion is imparted by straps or bands J, attached to pivoted levers K K', which are alternately` depressed and 'released by earns L L' on the driving-shaft E, the straps winding in reverse directions upon the shalt I or upon a hub secured thereon. The rock-shaft also carries a cam-wheel, M, the purpose ot' which will appear presently.

Before describing the tying mechanism in detail I would say that the two ends or strands of the applied band are iirst passed in a double or loop form through a strip of tape or fabric, thin metal, or other penetrableor perforated material. Then the strands, or the portions which subsequently become the ends of the applied band, are carried over and around the edge of the strip or tape, again doubled, and passed through the loop previously carried through the tape or strip, thus forming a single' bow-knot ot the two strands, into which the strip or tape is tied or incorporated topre! vent the slipping or drawing out ot' the knot.

Referring now to the drawings, N represents an overhanging arm, provided with a lateral extension or bed, N', at its outer end, directly over the compressor-cylinder, and projecting a short distance beyond the inner end of said cylinder, as shown. Upon thebed N' isinounted and arranged to slide an L-shaped arm,O, one portion of which lies upon the face of the hed, while the other portion drops down in front of the-forward edge of the bed, or in i'ront of an upright iiange or rib, d, formed thereon, and is armed with a steady-pin, e, and a notched needle, f, arranged to pass respectively through' the hole g and the notch or opening h in the rib or ange d, both passing through a strip or band, P, of tape or other material, fed along the upright face of the rib or iiange from a ieel or spool, Q, by the feeding device R. The artn O is formed with a straight slot, t', which, near the rear end of the arm, turns oif to one side, as shown in Figs. l and 3, and through or into this slot extends a cylindrical pin or stud projecting upward from the face of the bed N.

The rear end of arm O is jointed to a bar or rod, S, and this in turn to an upright lever, T, pivoted at its lower end to the frame A. rlhe leverT is connected by alink-bar with a similar lever, T', pivoted to the arm N at its upper end, and actuated by a crank or eccentric, U, on the main shaft E, to move the parts in one direction, a spring or other device being einployed to move them in the reverse direction, or the lower end ot' the lever T being slotted to straddle the crank and to'atl'ord the required play'of the saine.

From the above construction it follows that when the leverl is moved in one direction the aIrm'Q is caused to move outward until the pin e and needle fare entirely clear of the rib d, and then to swing to one side, as in Fig. 3, and

in Fig; 1.

that upon the reverse movement of said lever the arln is swung around, so that its forward portion is parallel with the rib or liange d and the pin e and needle fare in line with their respective openings, through which they are passed by the inward movement of the arm. The arm O also carries a blade or cutter, j, which passes through a slit or opening in the rib d as the arm is drawn in, and serves to cutfrom the strip P a short piece or section suitable for use in the formation of a knot, the strip being steadied and retained in place during the cutting by the pin c.

V represents a bracket-arm or overhan ging support, through which slides a rod or loar,`

W, which b ar is moved longitudinally by the cam-wheel M, previously mentioned, the edge ofthe wheel traveling between two studs or rollers, k, formed upon or attached to the lower side of said bar, as shown in`Fig. 1. The bar W carries an arm, X, which operates and conA trols the tape or strip feeder R, which latter consists of an elbow lever or dog, I, with a sharp nose or a roughened foot and pivoted at the angle or elbow to a sliding` block or plate, m. It will readily be seen that under this construction the retraction or movement of the sliding bar W toward the cylinder Gr will cause the nose of the dog l to be thrown against the tape or strip P by the arm Xand to move the stri p forward 5 but that upon the reverse movement ofthe bar the nose of the dog will be thrown away from the strip and the dog caused to move baci; without acting upon the same.

Upon the bed N' is mounted, in suitable supports or bearings, a shaft, y, carrying at one end a pulley or wheel, m', and at the opposite end fashioned into or provided with acircular needle or finger, n, notched in its outer surface near the point, as shown in Figs. 1,3, and

o. The movements ofthe bar W also serve to too IOS

impart a. rotary motion to this circulanneedle or tinger by means of a cord or band, o, passing about the pulley m' and around a second pulley, 1),.carried in a fixed support Va-t the outer side ot` the bed N', the ends ofthe band being secured to and carried bael; and forth by the bar, as shown in Fig. l.. y

The cord-holder H consists simply of a stationary and a pivoted jaw or finger, the latter held against the former by a spring, as shown The ends ot' the jaws are beveled to cause the eord to enter readily` between them and force them apart when sufticient pressure for the p urpose is exerted. l

A stationary euttingbla'de, Z, preferably having` its edge int-lined, as shown in Fig. 1, islocated in rear ot' the circular linger or needle it in the path of the binding-cord as it is carried back by the holder H.

Having now described the construction of the machine and its various parts, I will eX- plain the operation of forming and binding a bundle of grain, securing the band, severing the same from the twine upon the reel, and finally discharging the bound bundle.

. The strip P is fed forward across the open- IIO ings g h, and grain is swept by the rake into the compressor C, which closes tightly as the grain passes to its place therein, thus compressing the bundle-and rendering it iirm and compact. The cylinder G up to this time stands with the cord-holder in front of the compressor or toward the advancing front of the reaper, the cord passing down from its spool or reel through an eye or guide in the sliding arm W, over the opening h inthe face of rib or iiange d, and over strip P lying thereon, and thence under the bed N', back to the cordholder H. The grain being supplied to the cylinder or compressor C -and properly compressed, the cylinder G is caused to rotate and the cord orband is carried by the cord-holder H about the bundle7 passing between the compresser C and cylinder G andnpward to and across the opening h, the arm O being at this time thrown aside, as in Fig.3. When the second strand or end of the band is thus brought up by the cord-carrier H and laid beside the iirst, the lever T' is actuated and the arm O caused to swing over and to bring the steadypin e and needle f opposite their respective openings and then to move inward. In thus moving inward the notched needle f enga ges the strands or cords and pushes them in the form of a loop, p', through the strip I and opening h, as shown in Fig. (i, the strands above the strip being at the same moment across the circular needle or finger u, which thereupon rotates, bringing its notch u' opposite the strands or cords and permitting them to tall therein. The rotation of the needle or finger continuing, the strands are carried through the loop p a suflicient distance to form a full loop, q, whereupon, the rotation of the circular needle being reversed by the retraction of bar IV, the circular needle oriinger backs out through-loop p', leaving a bow-knot. J ust previous, however, to the backward rotation of the needle or iinger iz vthe strands or ends ofthe applied band aresevered by being carried against the fixed blade or cutter Z-by the further movement ofthe cordholder H. 1n carrying the second strand or end of the band up to the side of t-he first, and after the formation of the loop p', the cord-holder H comes into contact with the iirst or main cord passing fromv the reel, which cord, strikingbetween the beveled jaws, forces them apart and entersjust previous to the cutting of the applied band from the twine of the reel. In passing inward the arm O carries the cutter j with it, severing a short section from the strip I?, which is tied into a knot, as explained. lhns it will be seen that the knot is tied through and Varound the strip I), that a short section of the strip is severed from the main stock for this purpose, and that as the knot is completed the applied band is severed from the band material of the reel or spool. The applied band being cnt from the main supply or stock at a point below the cord-holder H when the latter is up, as in Fig. 1, it will be seen that the new end coming frornv the reel above will be retained bythe holder H, and carried `thereby to the position occupied at the comy mencement of the binding operation proper as the cylinder G is turned back to its liirst posi tion.

It is obvious that the details of the gearing or operating mechanism may belmodified, any usual or well-known mechanism for producing the motions peculiar to the different parts being employed, ifidesired, in lieu of that shown and described. y A

It is apparent that instead of operating the circular needle or finger u by means of the pulley and band, as described, a gear-wheel or pinion may be substituted for the pulley and a sliding rack-baror a curved rack attached to a swinging arm or lever employed to give motion to the pinion alternately in reverse directions, the rack bar or lever being connected with the driving mechanism in any usual or convenient manner to produce the alternate motion. Cams, links, or reversing-gear of any well-known form may be used for this purpose.

Any usual form of tension or take-up device, or both, may be employed, if desired. or nec essary. y

I am aware that the reversing vmechanism by which the cylinder is operated is not new per se; and I do not broadly claim the same, but only when used in connection with other mechanism or devices; nor do I broadly claim the feeding device by which the strip is fed or the mechanism for operating the same. r

I am also aware thatin sewing-machines a single strand of thread has been carried through and around the edge of the fabric in the form of a loop; but'I am not aware that the two strands have ever before been so mav nipu'lated, or that such plan has ever before been applied to the fastening of grain-bands.

Having thus described my invention, what I claim is- 1. In combination with a reaper, a grain bundling and compressing device composed of segmental sections C C', adapted and arranged tomreceive the grain at the end while closed, one of said sections being hinged to the other and adapted to open to discharge the bundle, substantially1 as described.
